ROTARY ENGIN E.

SPECIFICATION forming part of Letters Patent No. 502,818, dated August 8, 1893.

Application filed September 24, 1892- Serial No. 446,846. (No model.)

To all whom it may concern.-

Be it known that I, HENRY P. HOLLAND, of San Francisco, county of San Francisco, and State of California, have invented a certain new and useful Improvement in Rotary Engines, of which the following is a specification.

My invention relates-to improvements in rotary engines by the application of the power as a continuous uninterrupted force, bearing directly upon the pistons, acting thereupon without any break or check of the same to produce thereby a steady and rapid revolution of the engine, by means of which, ma-

chinery may be operated so as to save a large percentage of the power that is now lost in all other methods of its application. There is absolutely no out ofi or break of the force acting upon the pistons of the engine. Hence a much less force is required to accomplish the same results than by any other device now in use.- The engine may be operated most effectively by steam, water, compressed air, and gas, and may be used as an air compressor or water pump. The motive power employed enters the port inlet of the revolving cylinder, and escapes, (after acting upon the pistons that slide therein) by the exhaust port, operating with a direct and continuous push in its rotary circular movement, and with the full degree of volume of power applied. The power acts in combination with the centrifugal force produced by the rapid revolution of the cylinder or engine, to propel the same.

I attain the objects of my invention by the mechanism illustrated 'in the accompanying drawings, in which- Figure 1,-shows a transverse section of rotary engine on the line no. at. as seen in Fig. 3; Fig. 2,a plan of rotary engine; Fig. 3,a longitudinal section; Fig. 4,-view of port inlet or cylinder; Fig. 5,-view of exhaust port to cylinder; Fig. 6,a detailed view of piston slide and slide rings; Fig; 7,top view of piston; Fig. 8,-top view of slide.

The rotating engine consists of shaft B.

mounted in the bed piece A. and carrying at its end a cylinder 0. revolved by steam, water, air, gas or other power employed, passing into it through inlet port D, and out of it through exhaust port E, after acting upon the p st ns h slide in and-out of said cylinder;

and having the spider wheel H. fastened on small shaft d. being out of line with themain shaft, with arms 8.8. attached at their outer ends to the rotating ring slides or cam-way j. 7': said spider wheel with the said rotating ring slides acts as an eccentric with said main Shaft, and is revolved by it. The slides or cam-way h. are inclosed in ring slides or cam-wayj. j. and contain opening 0 through which the ends of the piston rods 6. I). pass and are fastened to it by nuts 9. p. and by means of this connection of the piston rods with the rotating ring slides or camway the pistons a a a a a a are moved in and out in the cylinder 0, as the shaft B, and the cylinder revolve. Through the opening 0. in the slides h. the guiding rods 0. 0. attached to, and governing the ring slides or cam-way and rotating them evenly pass, and are joined to the outer ring I; springs e. e. .are placed on the ends of the piston rods on each side of slides h. h. secured in place by nuts 19. 10.; m. m. projections to piston pieces extending upward on same and moving in grooves 12. 71.; q. q. bearings for small shaft; '1". flange to spider wheel; u. u. bolts fastening ends of guiding rods to outer ring, 1'. 'i. 'i. 1'. bolts that fasten bed pieces and support an inside cylinder wall together; f. packed joint in the cylinder for closing it tightly to prevent the escape of steam, air or gas, &c.; g. packingbox in the cylinder where the pistons slide. w. w. show line of transverse section of engine, to. driving pulley; F. rotating wall of cylinder; G. fixed Wall of cylinder; 4). outer circumference of cylinder; 7t. bearings to main shaft. The steam or motive power employed entering the inlet port of the cylinder strikes against the pistons 0?. 0d. partly closed, and a. wholly closed, revolving the engine rapidly, and asthe pistons a and a. partly closed (as shown in the drawings) rise by the action of the ring slides to which the ends of the piston rods are attached, escapes through the exhaust port, and by the rapid revolutions of the engine thesteam, water,'or power employed is hurled against the outer circumference wall of the cylinder, and against the pistons so as to add force, and greatly to accellerate the speed of the engine, thus. operating it by the power and centrifugal force combined.

The small shaft with the spider wheel acts as an eccentric with the main shaft and cylinder and operates the ring slides that work the pistons on the guiding rods, rotating said slides evenly. The driving pulley 10. attached to main shaft operates the machinery with which it is connected by belts or other connection. The springs on each side of slides h. h. act to prevent rigidity of the action of the pistons, so as to enable them to give passage for any obstructions that might enter the cylinder and be forced against them.

The inner and outer ring slides inclosing slides 7t. 77.. are retained in place by means of bolts. 8. s. are arms of spider wheel attached at the outer ends 10 the ring slides. The guiding rods to the pistons are attached at their outer ends to the outside ring and are secured at their other or lower ends to the outside of the cylinder near the packing box.
